Embodiment Construction

[0031] In the existing self-optimization network (SON, SelfOptimization Network) mechanism, in order to realize functions such as automatic configuration of the ENB neighbor cell relationship, such as figure 1 The shown SAE system architecture also includes an operation management and maintenance (OAM, Operations, Administration & Maintenance) server. Since the OAM server has a connection relationship with the MME Pool and the SGW Pool (such as image 3 shown), therefore, the embodiment of the present invention utilizes the OAM server to provide a target node selection scheme based on load information to solve the problem that the prior art does not provide a target MME or target SGW based on load information specific program issues.

[0032] The main realization principles, specific implementation modes and corresponding beneficial effects that can be achieved of the technical solutions of the embodiments of the present invention will be described in detail below in conjunct...

Abstract

The invention discloses a method for selecting a load information-based target node, which is applied to a system architecture evolution system. The method for selecting the load information-based target node comprises the following steps that: a target node selection device receives the load information of each mobility management node acquired and transmitted by an operation, management and maintenance server, and selects the mobility management node with the lightest load as the target node. The invention further discloses a device for selecting the target node and the operation, management and maintenance server. The technical scheme disclosed by the invention provides the load information-based particular scheme which realizes the selection of a target MME or target SGW.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for selecting a target node based on load information, and an operation management and maintenance server. Background technique [0002] According to the latest System Architecture Evolution (SAE, System Architecture Evolution) system protocol 3GPP TS23.401v8.2.0, the specific structural diagram of the SAE system architecture is as follows figure 1 As shown, in the system architecture, the main components include: multiple serving gateways (SGW, Serving Gateway), multiple mobility management entities (MME, Mobility Management Entity), multiple evolved base stations (ENB, Evolved Node B ) etc. (due to figure 1 The other constituent units in are less relevant to the solution provided by the present invention, and will not be described in detail here). Among them, the set formed by multiple SGWs to achieve load balance is called SGW Pool,...
